Big Bend Closes Some Areas in Early October to Protect Bighorn Sheep

If you're planning a fall trip to Big Bend, here's something worth building into your plans now. On September 25, 2026, the park announced that a wildlife management project is about to get underway. Temporary closures of certain areas are planned starting in early October. So it's worth keeping some flexibility in your itinerary if you're aiming for that stretch of the season.

The goal is an ecological one. The park and the Texas Parks and Wildlife Department want to protect the desert bighorn sheep, a species native to the region. To do that, they're working to reduce the presence of an introduced competitor, the Barbary sheep, also known as aoudad. This isn't a first. The two agencies run this effort together every year, which makes it a recurring part of how the park is managed.

In practical terms, that means some of the trails or areas you'd normally be able to reach may be closed while the work is underway. We'd recommend checking whether the spots you care about are open right before you head out, since the exact schedule can shift on the ground. A backup plan, another hike or another day, saves you an unpleasant surprise at the gate.

This kind of operation stays occasional, and it won't keep you from enjoying the park under good conditions. To get your bearings on the major areas, entry points, and highlights before you lock in your dates, lean on the Big Bend park guide, which will help you build an adaptable itinerary.
